Hi.
We use CCR1036-8G-2S+ devices. RouterOS v6.36.3. Our configuration has many simple queues (about 2000). Regularly we need to add/remove simple queues. Usually traffic is about 1 GBit/s and CPU load is below 40%. At this time simple queue additions and removals go well without any CPU usage spikes.
But at times when traffic grows and CPU load reaches 45-50%, something goes wrong. At this time each simple queue addition/removal causes CPU usage to go up to 100% and it stays like that for tens of seconds. Profiler shows that 70% of cpu is used by ‘Queueing’. At this time traffic drops to 200-300 MBit/s. Then CPU usage goes back to normal until next simple queue change.
Has someone faced similar issue?
We already have support ticket for it: Ticket#2016091922002019. But we don’t receive any reply for 10 days already. It seems support is out of ideas already.
